4 surgical additions to the spec, no task changes:
1. Result return type: Added a coordination note in §3.1 (Data-
Oriented Design) explaining that the shared send_openai_compatible
helper should return Result[NormalizedResponse, ErrorInfo] from
day 1, not NormalizedResponse + ProviderError raise. This is so
the downstream data_oriented_error_handling_20260606 track is
a small mechanical pass over new code, not a second migration.
References nagent_review Pitfall #4 (provider history divergence)
and the ErrorKind.PROVIDER_HISTORY_DIVERGED_FROM_UI use case.
2. Declarative read, not behavioral dispatch: Added clarification
to §6 (UX Adaptation) that the capability matrix is a *read* of
declarative data, not a new dispatch layer. Per nagent_review
Pitfall #1 (opaque function calling in the Application is the
correct choice; nagent-style protocol is for Meta-Tooling),
UI elements are visible/enabled/disabled/hidden but the
*behavior* they invoke is unchanged. Three concrete examples
added: screenshot button, cost panel, cache panel.
3. PROVIDERS source of truth: Added a NOTE in §3.2 (Module Layout)
that src/models.py:79-86 PROVIDERS is the existing single
source of truth for the (vendor, model) enumeration. The
capability registry reads from this constant rather than
introducing a parallel list. Cross-references
docs/guide_models.md.
4. Docs touchpoint: Expanded Phase 6 (Docs + Archive) in §9 to
note that docs/guide_ai_client.md needs the new providers +
the shared helper documented, and that
docs/guide_context_aggregation.md (added 2026-06-08) is the
reference for the aggregate.py pipeline that all new providers
use.
5. See Also cross-references: Added 3 new entries to §13.2:
- docs/guide_context_aggregation.md (the new pipeline guide)
- conductor/tracks/nagent_review_20260608/report.md (§1, §5, §15)
- conductor/tracks/nagent_review_20260608/nagent_takeaways_20260608.md
(§1, §2, §9)
No plan.md changes. Plan tasks are task-level and will flow from
the spec changes when the track is re-planned.
